Our 5 gallon pour spout comes with two threaded adapters. The larger black adapter screws onto 2-3/4 inch diameter threads, and the smaller threaded adapter screws onto 2-1/2 inch diameter threads. For plug type openings that do not have a threaded cap, do not use either adapter. Simply remove the plug from the bucket, and then push the spout into the hole until it snaps into place.
Made of heavy duty polypropylene, this durable paint pour spout will last for years. May be used with all water based, latex, or oil based paints. When using water based or latex paints, clean it with soap and water. When using oil based paints, clean it with mineral spirits (do not use turpentine). Model #30669-00778
